Nanotechnology in Modern Agriculture: Efficiency, Sustainability, and Future Prospects

Abstract Nanotechnology is revolutionizing modern agriculture by offering innovative solutions to critical challenges such as pest infestations, soil deterioration, environmental pollution, and inefficient resource use.This review explores the applications of nanotechnology in agriculture focusing specifically on nano-fertilizers and nano-pesticides as sustainable alternatives to conventional practices.Nano-fertilizers, designed with nanoscale particles, optimize nutrient delivery through controlled release mechanisms, ensuring higher nutrient use efficiency (NUE) while reducing nutrient losses and environmental contamination.These fertilizers address issues such as soil nutrient depletion, leaching, and excessive chemical use, thereby contributing to the restoration of soil health.Similarly, nano-pesticides, including nano-imidacloprid and nano-silica formulations, revolutionize pest management by providing enhanced bioactivity, slow-release functionality, and target-specific delivery.This approach reduces pesticide residues in the environment and minimizes harm to non-target organisms, offering a safer alternative to traditional chemical pesticides. In developing nations like India, where agriculture forms the backbone of rural livelihoods, nanotechnology can play a pivotal role in addressing food security challenges by improving crop yields, mitigating pest resistance, and enhancing soil fertility.However, the persistence of nanoparticles in the environment raises significant concerns, particularly regarding their potential to accumulate in soil, disrupt microbial communities, and introduce long-term ecological and health risks.This review highlights the dual-edged nature of nanotechnology in agriculture, where its benefits in improving efficiency and sustainability must be carefully balanced against its potential risks.While nanotechnology holds immense promise in driving sustainable agricultural practices and enhancing global food security, responsible implementation supported by comprehensive research into its environmental impacts is imperative to unlock its full potential
